This is the first telescope’s light FSQ106, after adding the focal reducer to fit into a 385mm focal length, as with the camera FLI8300, allows you to frame a truly spectacular wide fields, as in this case by photographing the nebulae classified as IC443 for the Nebula Medusa Jellyfish Nebula or in the right and the left IC444. The first is a planetary nebula, which sheltered a neutron star that exploded about 30,000 years ago and left a very large carryover, is located about 5,000 light years away. In the picture the nebulae are flanked by the stars Mu and Eta in the constellation Gemini. It’s a picture from 5:30 hours of exposure.
